Emotional mood states and memory: Elaborative encoding, semantics processing, and cognitive effort.

The effects of experimentally induced mood states on recall of target words embedded in sentences or alone were examined in three experiments. All experiments focused on the role of a depressed-mood induction on recall and looked at the effects of elaborative encoding, semantic processing, or cognitive effort. The overall effect of the depressed-mood state was to reduce recall in all three situations; however, the opportunity to process information semantically still led to superior recall in the depressed condition. In contrast, the superiority of recall of high-effort items disappeared in the depressed condition, suggesting that subjects may differentially allocate resources when under a depressed-mood state. The results are briefly discussed within the framework of a resource allocation theory.
